• Light insulating brick for metallurgical furnace
  • Application
    Cordierite coal light brick is used for lining heat insulation and heat preservation of airheater,heating furnace, coke oven and soaking pit. Light mullite brick is used for heating furnace, lining of soaking pit, door of coke oven
    High purity composite mullite and cordierite are used as host material, add light insulating brick gener-ated by cenosphere or light grain, it is of low coefficient of heat conductivity, high compression strength good heat stability and long service life, etc.
